Historic Rainstorm Hits Southern Colorado
US · Published Oct 30, 2026
• Southern Colorado experienced one of the most extreme rainstorms in state history from October 21 to October 25,
• The storm brought widespread heavy rainfall to the region, including neighboring areas of New Mexico, Utah, and Arizona. Influenced by remnants of Tropical Storm Trudy and El Niño conditions, the storm delivered up to 8 inches of rain in high elevations and 4-6 inches in lower areas. The San Luis Valley, typically a dry region, saw unprecedented rainfall, with some areas receiving over four times their usual October precipitation. Several locations, including Alamosa and Monte Vista, recorded their wettest two-day and three-day periods on record. The storm caused significant flooding, washing out roads, damaging homes, and requiring water rescues. Despite the destruction, the rainfall has substantially improved drought conditions across southern Colorado, with reservoirs like Navajo Reservoir seeing a much-needed boost in water levels.

Impact & Risks

The storm caused widespread flooding, leading to washed-out roads, damaged homes, and recreation areas. Communities in southern Colorado, including South Fork, experienced significant flood damage, with rainfall amounts exceeding 1000-year storm thresholds in some areas. While the rainfall has improved drought conditions, the floodwaters have disrupted daily life and infrastructure. Rivers that were near record-low flows during the summer are now near record highs, posing ongoing risks to affected areas. Another storm is expected to bring additional rainfall and flood risks to the region this weekend, particularly on November 1.
